SSR-Solid state relay:Advantage & disadvantage

Solid state re;lay has advantage over EMR or electromagnetic relay.
Advantage:

1. Has no moving parts thus immune to shock and vibration.
2. As an electronic device,it requires low voltage.
3. They are long lasting then EMR

Disadvantage:

1. Can be false triggered by electrical noise.
2. When on,there will be power loss due to some voltage drop.
3. Lethal leakage current when its off state.
